BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator cooling device for cooling a core multilayer radiator mounted on an engine of a working vehicle.

[0002]

2. Description of the Related Art There is known a cooling device for an engine mounted on a working vehicle using a core multilayer radiator. In this type, when dust enters a multilayer core portion, the dust is removed and cleaned. Becomes extremely difficult. In view of the above, conventionally, cooling air sucked from an intake port with a dustproof net in a machine room accommodating an engine is filtered by a filter provided on the downwind side thereof and supplied to a core multilayer radiator section. .

[0003]

In the conventional apparatus,
The cooling air that has passed through the air intake with dust screen is further filtered by a filter and supplied to the core multilayer radiator.
Although the intrusion of dust into the multilayer core is reduced,
Fine dust that has passed through the dust-proof net at the intake port adheres to the outer surface of the filter and causes clogging in a short period of time. The clogging hinders the passage of cooling air and cools the core multilayer radiator. There is a problem that the engine is overheated due to a failure.

[0004]

According to the present invention, a dustproof body made of a punch metal or the like is provided on the leeward side of an intake port with a dustproof net in a machine room accommodating an engine, and furthermore, the dustproof body is rotated on the leeward side of the dustproof body. A filter is provided so that the rotation of the rotary filter can always maintain a state in which poor cooling air does not pass.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a radiator cooling device according to the present invention, a core multilayer radiator and an outer periphery of an intake fan are surrounded, and a part thereof is provided in a cooling air suction passage to the core multilayer radiator. The located cylindrical filter is rotatably mounted around a pivot shaft so that it can be appropriately rotated by the power of a driving motor or the like or manually.

When the cylindrical filter is rotated by a driving motor or the like, the filter is constantly rotated, intermittently rotated at a fixed angle for a fixed time, or a degree of clogging of a portion located in a cooling air suction passage is detected. It is possible to take various forms as necessary, such as by detecting at −, and to rotate at a fixed angle based on the detection signal, and if a manual structure is used, it is located in the cooling air suction passage. It is preferable that the degree of clogging of the portion is detected by a sensor and an alarm is issued, so that the filter is urged to rotate.
